ASTAC Call for Proposals

ASTAC 2022-A (Q1-Q2)

The new ASTAC Call for Proposals closes at 8pm (AEST) Friday 26th November 2021

The Astronomy Supercomputer Time Allocation call for proposals for Q1-Q2 2022 is now open. The deadline for this call is 8pm (AEST) Friday 26th November 2021.

Within this call we have 6 million service units available to allocate to the astronomy community on national supercomputing facilities (including allocations for CPU-only and GPU-specific applications) and up to 500 virtual CPUs to allocate on OpenStack virtual machines on the NeCTAR network. 

The following resources are available:

  • NCI Astronomy Program: up to 4,000 kSUs on the Gadi system
  • Swinburne: up to 2,000 kSUs on OzSTAR
  • OpenStack Virtual Machines: up to 500 virtual CPUs.

You can access the information sheet for the current call here, including details on how to apply.

ASTAC is formed by Astronomy Australia Limited (AAL) and the ASTAC process is managed by Astronomy Data and Computing Services (ADACS).

AAL’s Astronomy Supercomputer Time Allocation Committee (ASTAC) allocates available time on the following supercomputer resources for dedicated national astronomy access:

  • OzSTAR, Swinburne University Supercomputer
  • NCI Gadi, NCI National Facility
  • ATHENA, Pawsey (when time is available)

Note: AAL will consider ASTAC allocating time on any other supercomputer resources that have dedicated national astronomy access, where appropriate.

There are usually two calls for proposals per year, announced around May and November, and closing in June and December. Please refer to ASTAC’s allocation principles.
